compiling error on gcc -m64 flag #2
Description
Converted from SourceForge issue 573005, submitted by nobody
I am running Solaris 9 with gcc version 3.1
at the Makfile change CCOPT to -O2 -m64.
If I delete the -m64 option, I could compile tcpdump
successfully.
the following error occurs:
print-esp.c: In function `esp_print_decodesecret':
print-esp.c:164: warning: cast to pointer from integer of
different size
